1. Different scales determine the occurrence of aquatic macrophyte species in a tropical stream
ABSTRACT Distributions of aquatic macrophyte species are commonly associated with water chemistry characteristics. However, other environmental factors that can lead to the occurrence of aquatic plants in lotic ecosystems, such as dynamic habitats linked to the surrounding landscape, have been underestimated. This study aims to evaluate landscape features th

2. White sand vegetation in an Amazonian lowland under the perspective of a young geological history
Abstract: What controls the formation of patchy substrates of white sand vegetation in the Amazonian lowlands is still unclear. This research integrated the geological history and plant inventories of a white sand vegetation patch confined to one large fan-shaped sandy substrate of northern Amazonia, which is related to a megafan environment. We examined flo

3. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

4. Sediment Morphology, Distribution, and Recent Transport Dynamics in a Reforested Fragment
Abstract Erosion generates large amounts of sediment, which may be deposited at the site of origin, on the slope of a hill, or along waterways. The transportability of each type of sediment by runoff and its potential for subsequent deposition largely depends on its morphological features and particle size distribution. The aim of this study is to describe a

5. Carbon pool ratios as scientific support to field morphology in the differentiation of dark subsurface soil horizons
In soil surveys, it is usual to find profiles with an uncommon disposition of horizons. Dark horizons in depth might be either the consequence of erosion and redeposition of soil materials from upslope or an indication of the podzolization process, which forms a spodic horizon. Few laboratory analyses are known to characterize dark subsurface horizons which

6. Estenose do canal lombar : relação do equilíbrio sagital com a avaliação clínica = Lumbar canal stenosis: relationship with the sagittal balance and the clinical evaluation / Lumbar canal stenosis : relationship with the sagittal balance and the clinical evaluation
There is a great variation in the results of previous studies analyzing sagital alignment parameters (SAP) in normal individuals and in patients with degenerative diseases of the lumbar spine. Most studies associate SAP only with chronic lumbar pain, in groups of patients with different lumbar degenerative diseases, which makes it difficult to apply these da

7. Remarks on the morphology and distribution of some rare centric diatoms in southern Brazilian continental shelf and slope waters
O trabalho apresenta informações morfológicas e sobre a ocorrência de diatomáceas atuais da família Asterolampraceae e de espécies de Azpeitia encontradas na plataforma continental e talude do extremo sul do Brasil no Oceano Atlântico Sul (28 -34ºS), sob influência de Águas Tropical, Subtropical e Subantártica, bem como do aporte terrestre do Rio

8. Mapeamento geomorfológico aplicado na análise de impactos ambientais urbanos: contribuições ao (re)conhecimento de morfologias, morfocronogêneses e morfodinâmicas do relevo da bacia hidrográfica do Arroio Feijó - RS / Geomorphologic mapping applied to the analysis of urban environmental impacts: contributions to the (re) cognition of morphology, morphochronogenesis, and morphodynamics of the Feijó/ RS stream basin relief
Urban environmental impacts generate various social disorders. In many cases, the analysis of environmental impacts should be the agenda for everyday discussion, included in urban planning policies. As support to these policies of urban planning in a perspective of applicability of geomorphologic knowledge we highlight the thematic mappings in geomorphology.

9. Estudo morfológico da bacia do Ribeirão do Baú São Bento do Sapucaí- SP / Morphological study of the basin of Ribeirão do Baú - São Bento do Sapucaí-SP
Este trabalho apresenta os resultados da cartografia morfológica realizada na Bacia do Ribeirão do Baú, Município de São Bento do Sapucaí, SP. Constitui um exemplo da aplicação da cartografia geomorfológica em um trecho da escarpa erosiva do Planalto de Campos do Jordão, compartimento morfoestrutural importante da Serra da Mantiqueira Oriental.

10. Influencia de la forma de los granos del fundente fundido CIS-F10 en la morfología y propiedades del metal depositado
In the present paper, the shape of fused grains flux CIS-F10, granulated in air and in water, its effect on weld bead geometry and its properties were studied. Grains morphology, properties, fluidity during piling, hygroscopic behavior and the amount of air between the grains during use were analyzed. The application of these procedures showed evidence that

Cefalostato virtual-posicionamento inicial para a padronização na marcação de pontos craniométricos em imagens obtidas por tomografia computadorizada, para uso em cefalometria / The Virtual Cephalostat - the preliminar adjustment for standardization of skull orientation in landmarks localization using CT in cephalometric analyses
Objective: The development of new technology in dental diagnosis by cone beam CT (CBCT) image, made possible and accessible the realization of cephalometric evaluation through volumetric reconstructions of the skull. Scientific parameters with evidence-based are needed to implement its use. Some parameters used in conventional cephalometry (2D) maybe need to

12. Sistema pedológico Planosolo-Plintossolo no Pantanal de Barão de Melgaço-MT / Pedological system Solonetz-Plinthosol in the Pantanal of Barão de Melgaço-MT
The Pantanal is the largest continental flood plains, comprising a mosaic of different habitats, maintaining plant diversity, animal and soil. It consists of eleven sub-regions, one of which the of the Pantanal of Barão de Melgaço, which is located north of the Quaternary sedimentary basin. It presents a spatial heterogeneity that is related to the diversi
